InkCut — Sketch to Stencil

About

From pencil line to cut line: InkCut vectorizes a photo, a scan or a finger sketch into a clean SVG, sized in real millimeters or inches. Download it free and start tracing straight away. Everything runs on your iPhone. Tune the trace, fix any node, check that a stencil holds together as one piece, then export a plain SVG, an actual-size PDF or a PNG preview. PICTURE IN • Photograph a paper drawing, open a saved JPEG, PNG or HEIC picture, or sketch with your finger • Crop, straighten and pull a skewed page square with perspective correction • Set threshold and contrast, clear specks, erase background areas or invert the fill before tracing • Split artwork into as many as six ink colors, each kept on a separate layer • Compare the source and the trace, then accept it as a new revision PATHS YOU CAN FIX • Move anchors, drag handles, insert or delete nodes • Scale, rotate, mirror, duplicate and align a selection • Union, difference, intersection and offset, each previewed before it lands • Simplify busy outlines, add basic shapes, undo and redo, save named versions STENCILS THAT STAY IN ONE PIECE • See what gets cut away and what material stays • Find loose islands, like the center of an O, before they fall out • Add bridges at the width you choose, then recheck every connection • Set a frame plus minimum detail and gap warnings to suit your own material FILES FOR THE NEXT STEP • SVG made of plain filled paths with its physical width and height written in: all visible layers together, or one SVG per layer • PDF at actual size, tiled across A4 or Letter with assembly marks and a 100 mm calibration bar, or fitted to one page • PNG preview for when you only want to share the look • Portable .inkcut project backups that stay fully editable THREE PANES ON IPHONE DUO Keep the original drawing, the vector canvas and the tool inspector open side by side. FREE TO START, PRO WHEN YOU ARE READY • Capture, cleanup, tracing in up to two colors, path editing and stencil bridges are all open in the free download • Your first three SVG or PDF exports are included; PNG previews carry a small InkCut mark • Pro is a single one-time purchase, not a subscription. It removes the export limit and the preview mark, and opens color separation beyond two layers • Want to test Pro on a real project first? The 7-Day Pro Trial costs nothing, never renews and asks for no payment • Bought InkCut before it became free to download? Pro is already unlocked for you, and Restore Purchases returns it if you reinstall No account and no ads, and tracing never leaves your device. WORTH KNOWING InkCut outlines filled shapes. It does not draw single-line centerline paths or rebuild editable text. It makes files only and never drives a cutting machine. A connected stencil is a geometry check, not a promise about material strength. After importing into other software, check the size and cut a small test piece first.
